This invention relates to a ring binder and more particularly to the means for securing the ring sections to wooden ribs.

It is an object of this invention to provide a ring binder with wooden ribs and steel ring sections secured to said ribs in an inexpensive manner. Other objects of this invention will become apparent upon lreading the following description, taken in conjunction with the accompanying drawings, in which: n

Figure 1 is a fragmentary top elevation of a loose leaf binder embodying the invention with parts broken away to more clearly illustrate the structure; l

Figure 2 is an end View showing the rings in closed position;

Figure 3 is a perspective view of one rib plate or toggle member;

Figure 4 is a perspective view of the ring carrying plate with ring section secured thereto being shown in dotted lines; and

Figure 5 is a fragmentary perspective view `showing .the ring carrying plate secured to the toggle plate.

In the drawings, the reference numeral 2 indicates a back member to which cover members 3 and 4 are hinged in any suitable' manner. A cover plate 5 is secured to the back member by means of a plurality of rivets 6. The cover plate is countersunk as indicated at 1, and the back member is countersunk,'as indicated at 8, to prevent the rivets from projecting beyond the top of the cover plate or the bottom of the back member.

A pair of wooden ribs or toggle plates 9 are arranged in side by side relationship in the cover member 5 with the downturned edges I0 and II ofthe cover plate embracing the outside longitudinal edges of the toggle plates. The toggle plates are strengthened by means of a longitudinal rib I2 which is integral with each toggle plate.

The reinforcement rib I2 is disposed approximately centrally of the toggle plate 9. 'Ihe toggle plate 9 is provided with a plurality of recesses I3 to provide clearance apertures for the rivets or eyelets G.

The longitudinal edges of each toggle plate 9 are notched to provide recesses I4 and I5. A

plurality of individual ring carrying plates I6 are i secured to each toggle plate 9 by means of a finger I1 embracing one edges of the toggle plate 9 and a pair of fingers I8Y embracing the opposite longitudinal edge of the toggle plate. The fingers Il and I8 are disposed within the coniines of the notches I4 and I5 so that none of them 55 2 project outside the planes of the longitudinal edges of the toggle plates 9. Ring sections I9 are secured in each ring carrying plate in any suitable manner.

Each ring carrying plate`I6` is provided with a finger 20 which projects over the edge of the oppositely disposed toggle plate. The ring carrying plate is provided with a. corner notch 2I to provide dearance for the projecting finger 0f the oppositely disposed prong carrying plate.

When the toggle plates 9 are arranged in side by side relationship with their outer longitudinal edges embraced by the edges I 0 and II of the cover plate 5A and the ring sections are moved to open position the cover plate restricts the movement of the toggle platesr and maintains them in proper Working relationship. When the ring sections I9 are moved from open to closed position, the interlocking fingers 20 engage the edge of the oppositely disposed toggle plate in the spaces provided by the recesses 2| to prevent relative displacement of the rinner edges ofthe toggle plates. The interlocking fingers maintain rthe side by side relationship between the toggle plates duringthe entire motion from one position ofV Lthe rings to the other. Each nger 20 acts as a vents the inner edge of the opposite toggle plate from slipping upwardly by the same engagement.

Although we have described a preferred embodiment of our invention in detail, it will be understood that the description thereof is illustrative, rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of our invention. Accordingly, we do not desire to be restricted to the exact construction described, except as limited by the appended claims.

We claim:

1. In a loose leaf binder, a pair of toggle plates, and a plurality of individual ring carrying plates each secured to one of said toggle plates, each of said ring carrying plates having a linger engaging said other toggle plate to restrain the downward vertical movement of said toggle plates.

2. In a loose leaf binder, a cover plate, a pair ofnon-metallic toggle plates arranged in side by side'relationship in saidcover plate, a plurality of metallic plates secured to each of said toggle plates, a ring section secured to each ofsaid metallic plates, and an integral linger on each of said metallic plates, said fingers engaging said tionship, said ring carrying plates each having an integral nger projecting over the toggle plate to which the opposed ring carrying plate is secured whereby said toggle plates are -interlocked 5 in Said cover plate.
